WRAPPING OR PACKAGING MACHINE.

To all whom it may concern! Be it known that I, GmnoNF. HALL, of the borou h of Brooklyn, county of Kings, State of ow York, have invented certain rov'ements in VVrap'pin or Iackagin- Mac ines, of which the f0 lowing is a full, clear,'and exact specification, such as will enable others skilled in the art to which it appertains to make and use My invention relates to certain improvements in the wrapping or packaging machines forming the subject of my coending application. filed Oct. 22, 1908, erial #458)82,- which is of that class wherein cams are provided and the article with its wrapper is moved past the cams so that the cams mo successively form the folds in the ends of t ie'wra per.

My present improvements involve varL one features by which the speed and certainty of operation are increased and the mechanism is simplified and rendered less cost] to manufacture, all of which features will fully set forth hereinafter and particularly pointed out in the claims.

Reference is now had to the accompanying drawings which illustrate, as an exam 1c, the preferred manner of practically em odying my invention.

In these drawings;Figure 1 is a lan view of the machine; Fig. 2 is {aside '12 evation of the same; Fig. 3 is a plan view with the top section'of the frame onwh'at is termed the table removed and other parts of the frame broken tral longitudinal section of "machine; Fig. 5 is a 'vertlcal cross-section on the line 5 5 of the-Fi 3; Fig. 6 is an elevation of the drive sh-a tend of the machine; Fig. 7 is a detail section taken longitudinally of the machine and particularly illustrating the device fol-driving the chain by the articles are advanced through the machine; Fig. 8 is a vertical cross-section on the line 8 -8 of Fig.3; Fig. 9 is a detailed vertical section on the line-9-9 of Fig. 1,

are, in the preferred fermof my invention,

carried continuously throu h the machine with a progressive step-h -step motion throughthe medium of an endless chain 21. running over sprocket wheels 22 and 23 and having its upper run or len h guided in a longitudinal slot 24 form in theoenter of the lamination 17 of the frame. This run of th e'chain is thus guided by means of stp ds 25'021 the chain, which are received in grooves 26 in the 'side edges or walls of the slot 24. In this mannerthe top run of the chain is held against vertical motion and- H support *for thearti-p ping operation. The

causedto form a firm cles during the wra. 4 chain is provided 'wit- .projecting fingers 2'7, fastened thereto at intervals and'servingto engage thearticles and push them forward.

28 indicates the prime mover shaft. which is mounted to rotate in bearings 29,- depending from the lamination 16. This shaft 28 is furnished with a. band wheel 30, or other means for imparting motion to it. Secured to the shaft 28 is a wiper cam 31 (see Fig. 6) which arranged to engage a toe "32 depending from a push rod 33 and by which the push rod is operated in one. direction. For returning the push rod 33 toward. the cam 31, said rod is provided with a spring 34 which may be arranged in any desired manner. One of the sprocket wheels 23.is fastened to a rotating shaft 35, suitably mounted in the rear supports 15, while the other sprocket 22 is carried on a shaft 36, mounted in the front supports 15. As

shown in Figs.- 7 ands, the shaft is provided with a disk 37, having at one side roller studs 38, adapted to be engaged by a toe 39 mounted with a knuckle joint on the push rod 33. As said rod reciprocates the toe 39 periodically engages the studs 38 and imparts a step-by-step rotation to the shaft 35, which results in a step-by-step motion of the chain 21 as before described. The shaft 28 also carries a wiper cam 40, which overlaps a spur ear 4&1, looseon the shaft: 36, and is adapte to on age studs 42 on the face of said gear. By t ese means the gear 41'is intermittently rotated; and in order to prevent idle motion of such gear a friction-spring 43is arranged to bear continually on the face of the gear. This gear 41 is adapted to drive the paper feed-roller 4A which, in the example here given, is accom- Above'the feed-roller f 48, the paper passing plis'hed'by a train of gears 45, '46 and 47. .44 is, a pressure-roller between these rollers from the paper roll 49 mounted in any del by a spring 55 bearing sired manner on the frame, for example, by

an arm 50. Said arm preferablv carries a guide or idler roller 51. By these means the aper is advanced in stages over the top of e machine and is automatically cut into len hs b devices which will now'be de; son 5 his cutting device comprises (see a transversely disposed which egztends over the to of the machine and 'coacts with a ledger lade 53, suitably provided on said top, As shown in 'Fig.

'11 the. lblade'fiil is mounted to swing vertically on a center 54 carried by the top section 19; andsaid blade is pushed upward under it. For pe riodically moving the blade 52 downward against theledger blade 53 I provide a rod 56 which is pivotally connected to the tang of the shear blade 52 andpr'bvided at .its lower end with transverse fingers 57' and 58. This rod 56 is vertically ided in thetop or body of the frame and its lingers 57 and '58 areadapted to be engaged by a push rod 59 .which is slidably mounted in the lami nation 16 of the body of. the machine (see Fig. 5). As shown in Fig. 11 the push rod 59 has a cam surface 59 adapted to engage a similar surface 58",0n the finger 58, thereby bringing about a downward motion of the rod 56 and the connected knife andcausing a short len'gh of paper, constituting the wrapper, to be sheared from the main body or supply of paper This operation is timed to take place immediately after the paper feed device has acted to advance the paper one step in its series of motions. The pushrod 59 is operated from a cam (50 on the shaft 28 which cam enga ges a too 61 depending from the front end of the push rod (see Fig. 6). Said rod 59 is returned against the cam by a spring suitknife 52 ably provided for that purpose,

The paper, as I have described, is fed over the to}; of the, machine and lengths are sheared o' td form the wrapper, such lengths lying, immediately after the shear ing operation, on the top lamination 19 between the led er formed on a inged into an opening in section 63 which is let the lamination 19 directly over the chain 21. Between the frec end of the hinged section 63 and the adjacentwall of sald openin in the lamination 19 a space 64 is provi ed through which I sipace the article and wrapper are moved blade 53 and a shoulder 62 ownwardly. Directly adjacent to the free end of the hinged, section mounted transversely insaid opening in the lamination 19, the purpose as well as that of the section 63, will be fully set forth hereinafter. The. article to be wrap ed is moved transversely over the to of t e machine and over the wra per w ich lies in the position above descri )ed. The article ma be so, moved manually, but I prefer to fee in the article automatically by a slide 66 dove-tailed in the upper surface of the table 20 and provided with an ugilward projection 67 to engage the article. e articles are, fed manually to: the slide which periodicall places one of" them in position. L'Ihe sli e 66 is operated back and 63 a roller 65 is' of which roller,

forth by a lever 68 joined to the underside of the slide and in tiprn actuated-b a rod 69 driven from a slide rod 70. The s ide rod crates in the lamination 16 alongside of t e slide rod 59 and is driven from a cam 71 on the shaft 28. This cam actuates the rod 70 through a toe 72 depending from the front-end of the'rod. a

By means of the slide 66 the articles are moved horizontally into position for move-' ment downward; and devices are rovided for receiving the article from the s downward motion of These devices for so rek proper time for the the article occurs.

ceiving thearticle consist in opposing aws 73 which are yieldingly connected to move toward and from eac pins 74 see Fig. 1). This 1' ding connection o the jaws 7 3 allows t em notfl nly to receive andv hold, the articles, but to accommodate themselves 9, the jaws 73 are supported in an 0 er hangin arm 75 carried by the laminatl m 19; an between the said jaws a lunger 76 operates vertically and periodi'c'a purpose of pushing the article do and holding it until the slide is retracted and the l for the mm the laws downward through the opening 647.

other live rings and i to variations in the size of the articles As shown best in Fig? corresponding surface on a P1181 rod 81 83 depending from the ash ro fore follows that at t -e proper time 1n 'under the roller and which works horizontally in the lamination 16v and is driven by a cam .82 on the shaft 28, said cam enga ing a toe (E t therethe cycle of operations the article is pushed from the jaws 73 downward with the wra per into the opening 64 and throulgll t e same to a positionpn the chain 21. edlstance between the roller 65' and the opposite wall or the opening 64: is approximately. equal to the width of the article so that as it is moved. downward theside edges of the wrapper are folded up and the article lies on the chain with the wrapper in U-shaped form under and around it. At this instant the chain 21 advances a step in its series of movements and one side ed of the wra per in passing under the roller 65 is folded own on top 0 the article as said article moves hinged section 63. By hinging the section 63 it is allowed to give to accommodate various sized articles.

Simultaneously with the abovedescribed movement of the article with the chain the second or remaining side edge of the wrapper must be folded down on the article; and this is accomplished by a slidin folderplate which, at the beginning of t e movethe article.

' laminations 18 and 19. The slide links 92 which -tion 19 and extend forwar plates. As indicated in Fig. 4, the links 92 ment of the chain, moves forward over the article faster than the chain and folds down the flap as described. Said folder plate is indicated at 84 in'the drawings The plate 84 is mounted under-the lamination 19 and directly over the edge-folding fingers 85. The fingers '85 lie on edge para el with and at opposite sides of the-chain in the lon'gitudinal opening 86 formed in the lamination 18 and constituting the passagewa through which the article moves with 't 'e' chain. Said fingers move in unisonwiththe'plate 84 and, simultaneously with the operation of said plate, serve to an age opposite ends of the wrapper and tuck t e same in against The )late s4'is fastened, as indicated at 87 in 1g. 3,, to the upper edge of one of the fingers 85 and moves with the same transversely as well as longitudinally. Said plate, however is'free to move transversely' independently of the other plate 85.

5 shown in Fi 12,the fingers 85 carry at their outer sid os transversely projecting arms 88, which arms lie under transversely disposed slide plates 89 fitted between the lates 89 have longitudinal slots 90 in wliich are movable pins 91 attached to the said-arms 88 of the fingers 85. The pins 9] are joined. to lie in a cavit in the laminad from the slide have their front ends pivotall connected with pins 93 carried on upwar extensions 94 of push rods 95. Said push rods are twp in number and arearranged to slide horizontally in cavities in the lamination 16. Push rods 95 are provided at their front ends with downwardly extending toes 96 ada she 28. .The ward the cams in any suitable slide plates 89 are engaged by pins 99 which, as shown best in Fig. 5, are carried by push rods 100 operating in the lamination 18. These push rods are held inward with a steady pressure by weights 101 hung from arms 102 on'roc'k-shafts 103, the rock-shafts having arms 104 engagin the push rods. This serves to hold the sli e-plates 89 yields ingly inward; and through the medium of the slide-plates the fingers 85 are. also held push rods 95 are returned toy springs 98 acting thereon ted to be actuated by cams 97 on: the

It now remains to fold upward and downward theend's of the wra the top and bottom sides of the artic wear! this is accomplished by oppositely disposed cams 108 and 109. These cams are situated in the passage 86 in the line of travel of the article so that as the article moves past them they engage the edges of the wrapper thou lying in the top and bottom planes of the article and fold said edges respectively upward and downward thereby completin the folding operation.
